Expose metrics with labels according to ETSI TS 128 552 V16.13.0 in
UPF by using hash.
The metrics are named respecting the rule:
<generation>_<measurement_object_class>_<measurement_family_name>_<metric_name_as_in_TS_128_552>
5qi is not available in UPF.
To present 5qi to the user, MN will have to maintain a table qfi->5qi
for each QoS flow (will have to get information from SMF).
So UPF has to expose qfi. qfi itself is not useful. When used, UPF will
have to expose additional label to define the session (e.g. source
interface).
Label dnn is set to value of APN/DNN received in Establishment.
Since SMF does not add APN/DNN to Establishment, the label is empty.
When APN/DNN will be set by SMF, it should be added to sess in UPF
and used in metrics on Modification and Deletion.
Both datavolumeqosleveln3upf are exposed in bytes.
MN is providing the transformation to kbits.
fivegs_upffunction_upf_qosflows should expose the number of QFIs used in
sessions, but exposes number of QER rules, which is currently equal to
QFIs.
The label snsssai is not provided since the slice is not available on UPF.
Exposed metrics example:
Standard counters:
fivegs_ep_n3_gtp_indatapktn3upf 28637

fivegs_ep_n3_gtp_outdatavolumeqosleveln3upf{qfi="1"} 737548
Nonstandard gauge (added for controlling purposes -
same metric as existing metric on AMF and SMF):
fivegs_upffunction_upf_sessionnbr 1
Standard gauge:
fivegs_upffunction_upf_qosflows{dnn=""} 1
